There were a lot of Catholics burnt at the stake also! How about Joan of Arc, who was but one of many? Also, how about the Catholics who died along w/Jews in the Holocaust? There was a large number of Catholic priests and monks who died when Henry the Eighth, (who started his own church)went on a rampage on the monasteries!
In reply to your question. It does not matter happened to Catholics when they did not have the power. It matters what the Catholic Church has done when it held on to the levers of political power. The historical fact is that the Catholic Church was directly responsible for killing people that did not agree with its doctrine. They had the power they had a choice, and in the past the Church chose to murder people. Granted it does not do or advocate these things today. But the Church expressly decided to kill against the will of Christ. I do not align myself with an organization that has such a history. I am a Christian but I would disavow the Church I am affiliated with in heartbeat if it advocated in the now or if it was ever proven that it had a history in the past, of murdering people.
